SMD0805P075TF 产品概述

一、产品简介

SMD0805P075TF 为 RUILON(瑞隆源)生产的 0805 封装自恢复保险丝(Polyfuse),适用于低压电子线路的过流保护。器件在过流时自动增阻限流,故障解除后可自动恢复导通,便于重复使用和维护,适合体积受限的移动设备与消费电子产品。

二、主要规格参数

  • 最大耐压(Vmax):6V
  • 最大电流(Imax):35A(短时冲击能力)
  • 保持电流(Ihold):750mA(正常工作不触发)
  • 跳闸电流(Itrip):1.5A(典型动作点)
  • 功耗(Pd):600mW(额定功率)
  • 初始态阻值(Rmin):70mΩ
  • 跳断后阻值(R1max):385mΩ
  • 动作时间:200ms(典型)
  • 工作温度:-40℃ ~ +85℃
  • 外形尺寸:2.2mm × 1.5mm × 1.0mm(0805 封装)

三、主要特性

  • 小体积、高密度,适合贴片自动化生产;
  • 重复自恢复,无需更换,降低维修成本;
  • 初始阻值低,能在不影响正常工作电压的情况下提供保护;
  • 对短时浪涌具备较好承受能力(短路时短时间允许较大电流);
  • 宽温度范围适应各种环境应用。

四、典型应用场景

适用于移动设备供电线、背光与显示驱动、USB 及外设保护、电池管理系统(BMS)低压侧保护、板上局部电路与模块输入保护等,对体积和可靠性有较高要求的消费电子、物联网终端与工业便携设备。

五、封装与使用建议

  • 0805 标准贴片尺寸,兼容常规贴片工艺;建议按制造商推荐回流温度曲线焊接,避免长时间高温滞留;
  • 器件应串联在受保护回路靠近电源入口处,且保持良好散热环境以提升触发一致性;
  • 对于连续高功率场合,应考虑器件发热与周边元件的热耦合,必要时选用并联或更高规格保护器件。

六、选型与注意事项

  • 确认工作电流低于 Ihold,避免误触发;若有大电流瞬变,需核算器件对短时浪涌的承受能力;
  • 在高温环境下 Ihold/Itrip 可能偏移,设计时留有充分裕度;
  • 注意电压等级 Vmax,若系统存在大于 6V 的情况需选择更高耐压器件。

七、可靠性与检测

常规质量保证包括寿命循环、过流-过温触发测试及跌落震动测试等。量产前建议在目标应用环境下做整机级联动验证,重点关注长时间通电下的温升与响应一致性。

八、包装与订购

封装:0805(贴片);品牌:RUILON(瑞隆源)。常见包装为卷带(Tape & Reel),便于 SMT 自动化上料。订购时请确认型号 SMD0805P075TF 与所需批次的规格一致,并索取最新的规格书与回流焊接曲线。

Sourcing availability signal

Stock routes, quotation confidence, lead-time notes, and shipment feasibility are checked before sales follow-up.

Buyer sourcing scenarios

Examples of how common component sourcing requests are organized.

Typical RFQ scenarios based on the WMSIC form fields, catalog data, manual review steps, and shipment preparation workflow.

The buyer shares the full part number, package requirement, quantity, destination, and available product photos so the quotation can record the exact version under review.

Package confirmation Typical RFQ workflow

A multi-line BOM is organized into direct sourcing lines, lines that need package clarification, and lines where alternative-part review is permitted.

Mixed BOM triage Typical RFQ workflow

The original manufacturer part number, datasheet revision, application, critical limits, and acceptable changes are collected before possible candidates are discussed.

Obsolete-part review Typical RFQ workflow

Sample quantity, minimum packing, package format, target date, and courier destination are kept together in one RFQ conversation.

Small-batch request Typical RFQ workflow

Package photos, model markings, board context, and the quantity needed for repair help focus the sourcing review on the relevant version.

Repair batch evidence Typical RFQ workflow

When a suffix or package note is incomplete, the response records the open difference and requests buyer confirmation before procurement proceeds.

Model suffix clarification Typical RFQ workflow

Packing format, carton notes, invoice details, courier option, destination, and tracking handoff are coordinated around the confirmed order.

Export handoff Typical RFQ workflow

The request connects the previously used model, current demand, package evidence, target timing, and replenishment sourcing route.

Replenishment inquiry Typical RFQ workflow
